Let's see how to reset the service light on the Mercedes Citan, which shares many components with the Renault Kangoo. The standard procedure involves turning on the dashboard, and on the steering wheel press the "ok" button (or "menu", depending on the version) to access the main menu.

Navigate to the "service" or "assyst plus" option, using the arrow keys on the steering wheel. Select "reset service", and hold down the "ok" button for a few seconds, until a confirmation message appears.

Alternatively, we can turn off the vehicle completely and hold down the "ok" button on the steering wheel: while holding it down, turn on the ignition. The display will show "service confirmation" or "reset". Turn off and restart for confirmation.
